Key result
Melting / freezing pt.:
< -100 °C
Atm. press.:
993 hPa

Results

During the cooling and the subsequent heating phase (thermograms of the DSC runs PN9487 and PN9488) no thermal effects were observed in the temperature range from -100 to 25 °C. It can be assumed that the test item has no melting or freezing point in this temperature range. Therefore the test item has no melting point down to a temperature of -100 °C.

 

Final Results

The test item has no melting point down to a temperature of -100 °C at atmospheric pressure (993 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).

Conclusions:
A melting point value of <-100 °C (at 993 hPa) was determined for the test substance according to E.U. Method A.1.

Description of key information

Melting point: <-100 °C at 993 hPa (EU Method A.1, differential scanning calorimetry)

Key value for chemical safety assessment

Additional information

A melting point value of <-100 °C (at 993 hPa) was determined for the test substance according to E.U. Method A.1.
